  Review Task Group Configuration: Check the configuration of the task group associated with the node in question. Look for any circular dependencies and correct them.
  Analyze Dependencies: Use the task dependency analysis tools available in SAP to visualize and analyze the dependencies between tasks. This can help identify where the loop is occurring.

  Testing: After making changes, test the task group to ensure that the loop has been resolved and that tasks can execute as expected.
  Consult Documentation: Refer to SAP documentation or notes related to task group configuration and dependency management for additional guidance.
